Silane (SiH4)

Magadzirirwo ehunyanzvi

Silane musanganiswa wesilicon nehydrogen. Izwi rekuti "compound" dzakasiyana-siyana, dzinosanganisira monosilane (SiH4), disilane (Si2H6) uye mamwe ma "silicon-hydrogen compounds" epamusoro. Pakati pawo, monosilane ndiyo inonyanya kushandiswa, dzimwe nguva inonzi silane muchidimbu. Silane igesi isina ruvara ine hwema hunonyangadza hwegariki. Inonyungudika mumvura, inenge isinganyungudike mu ethanol, ether, benzene, chloroform, silicon chloroform uye silicon tetrachloride. Hunhu hwemakemikari e "silane" hunoshanda zvakanyanya kupfuura ma "alkanes" uye hunogona kuoxidized nyore nyore. Kupisa kwega kwega kunogona kuitika kana kwasangana nemhepo. Haisangani nenitrogen iri pasi pe25°C, uye haisangani ne "hydrocarbon compounds" patembiricha yemumba. Moto nekuputika kwe "silane" zvinokonzerwa nekuita neoxygen. Silane inonzwa zvakanyanya kuoksijeni nemhepo. Silane ine huwandu hwakati ichaitawo oxygen zvakanyanya patembiricha ye -180°C. Silane yave gasi rinokosha rinoshandiswa mumabasa e semiconductor microelectronics, uye inoshandiswa mukugadzirira mafirimu akasiyana-siyana e microelectronic, anosanganisira single crystal films, microcrystalline, polycrystalline, silicon oxide, silicon nitride, uye metal silicides. Kushandiswa kwe silane mu microelectronic kuchiri kukura zvakadzama: epitaxy inodziya zvishoma, epitaxy inosarudzwa, uye heteroepitaxial epitaxy. Kwete chete kumidziyo ye silicon uye silicon integrated circuits, asiwo kumidziyo ye compound semiconductor (gallium arsenide, silicon carbide, nezvimwewo). Inoshandisawo superlattice quantum well materials. Zvinogona kutaurwa kuti silane inoshandiswa munenge mune ese ma integrated circuit production lines munguva dzazvino. Kushandiswa kwe silane se silicon-containing film uye coating kwakawedzera kubva muindasitiri ye microelectronics yechinyakare kuenda kuminda yakasiyana-siyana yakadai sesimbi, michina, makemikari uye optics. Imwe nzira inogona kushandiswa ye silane kugadzirwa kwezvikamu zve ceramic engine zvinoshanda zvakanyanya, kunyanya kushandiswa kwe silane kugadzira silicide (Si3N4, SiC, nezvimwewo) micropowder tekinoroji yakakwezva kutariswa kwakawanda.

Kushandiswa:

① Zvemagetsi:

Silane inoiswa pa polycrystalline silicon layers pa silicon wafers pakugadzira semiconductors, uye sealants.

②Zuva:

Silane inoshandiswa mukugadzira mamodule emagetsi ezuva (solar photovoltaic modules).

③Maindasitiri:

Inoshandiswa muGirazi reGreen rinochengetedza Simba uye inoshandiswa pakugadzira firimu rakatetepa.

Pakeji yakajairika:

Zvakanakira:

①Makore anopfuura gumi ari pamusika;

②Mugadziri wezvitupa zveISO;

③Kutumira nekukurumidza;

④Manyuko ezvinhu zvakabikwa akagadzikana;

⑤Sisitimu yekuongorora yepamhepo yekudzora mhando padanho rega rega;

⑥Kushandiswa kwakawanda uye kwakanyatsorongwa kwekubata silinda usati wazadza;

⑦Kuchena: kuchena kwakanyanya kwemagetsi;

⑧Mashandisirwo: zvinhu zvemagetsi zvinoshandisa solar cell; kugadzira polysilicon yakachena kwazvo, silicon oxide uye optical fiber; kugadzira magirazi ane mavara.
